Tyrosine Phosphatase Screening and Profiling Service

Creative Biogene provides multiple tyrosine phosphatases (PTPs) screening and profiling services to accelerate your research and drug discovery program. Our talented scientists with years of experience will offer specialized and fully defined services for screening potential modulators of PTP. As a pioneer in this field, we establish an efficient screening and profiling platform based on biochemical and cellular phosphatase assays. On this basis, we will assist you with the most affordable and high-quality service to ensure your satisfaction in a timely and professional manner.

Protein tyrosine phosphatase (PTP) is a kind of enzyme that remove phosphate groups from phosphorylated tyrosine residues on proteins. It is a signaling enzyme that, together with protein tyrosine kinase (PTK), regulates tyrosine phosphorylation inside the cell. Protein tyrosine phosphorylation is essential for the initiation, propagation, and termination of signal transduction in response to growth factors, hormones, cytokines, and cell−cell contacts. Aberrant tyrosine phosphorylation, resulting from alteration of PTP expression, misregulation and mutation, has been linked to the etiology of many human ailments including cancer, diabetes/obesity, autoimmune disorders and infectious diseases. Therefore, it becomes very important to screen effective and safe compounds in the discovery and development of targeted drugs. Some small-molecular compounds are reported as PTP modulators, which play an important role in targeted therapy area.
